NOTES ON SOME ADDITIONS TO THE FI.ORA OF 



COUNTY UMERICK. 



BY M. C KNOWI.es. 



Since June, 1902, Miss Charlotte O'Brien of Ardanoir, Foynes, 

 has been working steadily at the flora of the Barony of Shanid, 

 the north-western portion of County Limerick, and has been 

 sending me from time to time plants from this district. 

 Among those sent last year were a good number of those on 

 Mr. Praeger's list of desiderata for the county, as well as some 

 of the rarer species that had not been previously recorded from 

 it. These have been already published by Mr. Praeger in his 

 list of "Additions to Irish Topographical Botany in 1902" 

 {Irish NahiralisU January and February, 1903). 



The plants mentioned in this short paper have all been 

 found during the present year, andfor the sake of convenience 

 I group them under three heads; — (i) Those found by Miss 

 O'Brien in the spring ; (2) those found by Miss O'Brien and 

 myself during three weeks I spent at Ardanoir last June : (3) 

 those from other parts of the county found by Mr. R. D. 

 O'Brien of I^imerick. 



In the spring Miss O'Brien began collecting early, and in 

 March sent me Montia fo7ita7ia and Viola palustris from the 

 hills behind Ardanoir. About the same time she sent me 

 plants of the spotted form of A72cm maculatzwt. In some of 

 these the vSpathes were spotted as well as the leaves, which is 

 rather unusual, and the leaves showed the pseudo-blisters to 

 which Mr. Colgan has drawn attention. As Mr. Phillips in 

 his " Notes on Ancm 7naculatum'^ in Irish Naturalist, August, 

 1903, says he has not been able to find the spotted form on the 

 limestone crags or near the sea, I asked Miss O'Brien for 

 particulars as to the places she has found it about Foynes, 

 which is mostly on the limestone. She says " As regards 

 spotted Arum. It is very rare indeed on limestone, though I 

 have found it. It is mainly a product of dry stony ground — not 

 limestone. I have not seen it, or looked for it, near real sea ; 

 here it grows within 3 feet of seaweed, but this is not a true 

 sea place, though sea plants grow here." In April, Miss 

 O'Brien s^nt me a further lot of plants, among them Viola
